Abstract
The utility model relates a to an outside heating rotary kiln and in particular to an outside heating rotary kiln which is applicable to calcine the coal high mountain rocks. The tube of the outside heating rotary kiln of the utility model is divided to a plurality of sections; each section is provided with a driving device, a heating device and a supporting device; the joint part of the two sections is provided with a material transmission device. The utility model is able to carry out the calcining process strictly and accurately according to the material calcining principle to ensure the quality of the produce and the stability of the product, and enhance the energy output.
Description
Technical field
The utility model relates to a kind of outer heating rotary kiln, especially for the outer heating rotary kiln of calcining coal-series kaolinite.
Prior art
China has abundant coal series kaolin rock resource.Calcined kaolin can be made raw material with coal series kaolin rock (gangue), processes through distinctive technological process.But the production technology of calcined kaolin falls behind, and has many problems.The production technology backwardness mainly is the restriction that fallen behind by equipment.
The critical process that calcined kaolin is produced is heat treatment (calcining) modification, and key equipment is a calciner---kiln.Because it is at the early-stage that China was used for the development work of the special-purpose kiln that calcined kaolin produces in recent years, thereby, the enterprise that produces this series products for a long time just can only adopt the calciner of relevant industries (mainly being pottery and metallurgical), as tunnel cave, down-draft kiln and inside burning type rotary kiln etc.Recent years again from external introduced several outside the heating rotary kiln.When all these calciners are used to produce the calcined kaolin of ultra-fine, high whiteness, all exist problem to be solved.
When adopting tunnel cave or down-draft kiln, material be adorned casket Bowls or be made the anvil base and reenter the kiln calcining, not only unnecessary workload is big, and heat transfer efficiency is low, thereby output is lower, realize also difficulty of the serialization of production process and automation.
Rotary kiln is compared with preceding two kinds of kilns, and the thermal efficiency is higher, can carry out continous way production, and the electrical control degree is higher, and automatization level also can be improved.Especially after having adopted the rotary kiln of outer heating, solved the wearing and tearing of the combustion product of fuel and kiln lining, broken pollution problem, gone a step further before making rotary kiln aspect the technological rationality that is used for calcined kaolin production material.
But the present rotary kiln that adopts uses with relevant industries are long-term, and traditional rotary kiln is similar, after copying mechanically, according to the basic demand of nonmetallic ore calcination process such as coal series kaolin rock, substantial improvement is not made in the design of rotary kiln.Simultaneously, outer heating and the contradiction that improves the equipment capacity kiln of external introduction (for example from) are also better solved.
When at present used rotary kiln was used for calcining coal-series kaolinite, the subject matter of existence was: (1) can not be according to the requirement of calcining coal-series kaolinite mechanism, easily and accurately adjusting process and device parameter; (2) production capacity is lower; (3) in the time of will improving equipment capacity thereby increasing specification, the amplification of equipment manufacturing cost is bigger.
All existing rotary structures comprise equipment such as cylindrical shell, heater, drive unit, supporting arrangement, kiln hood cover, kiln hood.
Summary of the invention
The technical solution of the utility model is: cylindrical shell is divided into multistage, and every section is disposed drive unit, heater and supporting arrangement; Two sections connection places are provided with device for transporting objects.
Device for transporting objects can be designed to two sections cylindrical shell connection places wherein that the inwall of one section cylindrical shell end is fixed with conveyor screw, and this conveyor screw stretches in another section cylindrical shell, is with fixing hopper outside conveyor screw, is provided with sealing device between hopper and two sections cylindrical shells.
Another improvement is that an end of a forward cylindrical shell has up receiving opening on hopper.
For obtaining good sealing effectiveness, between two sections, be provided with and maintain static moving connection cover; The cylindrical shell end with connect the cover connection place be provided with sealing device.
The combined type that the utility model provides drive segment respectively heats rotary kiln outward, and particularly using it for the coal series kaolin rock is raw material when producing high-grade calcined kaolin, and following remarkable superiority is arranged:
1, each assembled unit of this rotary kiln, cylindrical shell shape be simple (cylindrical) all, and parameter and material can determine respectively that to the requirement of each unit rotating speed and heating-up temperature can be regulated respectively as requested according to calcining mechanism.The calcine technology of whole kiln can be controlled and be regulated by a central control device, thus make calcination process can be strict, carry out according to the requirement of material calcining mechanism exactly, the quality of product and stability thereof are reliably guaranteed.
2,, just can make production line realize " line fecund product " by " menu " option of automaton---on same production line, go out the product of the different trades mark with different technology, device parameter produced in series.
3, under the little condition of equipment manufacturing cost amplification, can make the production capacity of equipment that by a relatively large margin raising is arranged, manufacturing, transportation, installation and maintenance are also fairly simple easily.
4,, provide an otherwise effective technique approach for high-quality, carry out high-grade calcined kaolin production and enlarge its scale efficiently, reliably.

The specific embodiment
Fig. 1 is the structural representation of an embodiment of the utility model, this example be a kind of be used for the coal series kaolin rock be raw material produce high-grade papermaking paint level calcined kaolin combined type respectively drive segment heat rotary kiln outward, form by 2 unit combination.Cylindrical shell 2 is different with 7 diameter.Every section cylindrical shell disposes drive unit 12,15 respectively, and rotates by speed separately by gear-wheel gear-ring 3,10 and rolling ring 4,8 drive cylindrical shells 2,7.Supporting arrangement 13,14 is supporting cylindrical shell 2,7; Two sections connection places are provided with device for transporting objects 16.Two heating furnaces 5,9 are resistance furnace, as shown in Figure 2.
As shown in Figure 3, device for transporting objects is that the inwall of one section cylindrical shell 7 end therein is fixed with conveyor screw 16, and this conveyor screw 16 stretches in another section cylindrical shell 2, is with to be fixed on the hopper 17 that connects on the cover 6 outside conveyor screw 16.Between hopper 17 and the two sections cylindrical shells, and connect between cover and the cylindrical shell 2,7 and be equipped with sealing device.General encapsulating method is to adopt labyrinth sealing.Hopper 17 is a receiving opening that makes progress at cylindrical shell 7 one ends, is beneficial to material and enters hopper 17.This receiving opening is an angle.
Two unit are controlled by a central control device.
Passed through the granular material of a series of processing, entered cylindrical shell 7 through kiln hood 11 by charging (feeding) equipment, finish deshydroxy after, enter next unit through connecting cover 6; After in cylindrical shell 2, calcining fully, through 1 discharging of kiln hood cover.
